Perl 5.26 container image
This container image includes Perl 5.26 as a S2I base image for your Perl 5.26 applications. Users can choose between RHEL, CentOS and Fedora based builder images. The RHEL images are available in the Red Hat Container Catalog, the CentOS images are available on Docker Hub, and the Fedora images are available in Fedora Registry. The resulting image can be run using podman.
Note: while the examples in this README are calling
podman, you can replace any such calls by
docker with the same arguments
Perl 5.26 available as container is a base platform for building and running various Perl 5.26 applications and frameworks. Perl is a high-level programming language with roots in C, sed, awk and shell scripting. Perl is good at handling processes and files, and is especially good at handling text. Perl's hallmarks are practicality and efficiency. While it is used to do a lot of different things, Perl's most common applications are system administration utilities and web programming.
For this, we will assume that you are using the
rhscl/perl-526-rhel7 image, available via
perl:5.26 imagestream tag in Openshift.
Building a simple perl-sample-app application
in Openshift can be achieved with the following step:
``` oc new-app perl:5.26~https://github.com/sclorg/s2i-perl-container.git --context-dir=5.26/test/sample-test-app/ ```
The same application can also be built using the standalone S2I application on systems that have it available:
``` $ s2i build https://github.com/sclorg/s2i-perl-container.git --context-dir=5.26/test/sample-test-app/ rhscl/perl-526-rhel7 perl-sample-app ```
Accessing the application:
$ curl 127.0.0.1:8080
To set environment variables, you can place them as a key value pair into a
file inside your source code repository.
Allow the installation of all specified cpan packages and the running of their tests. The default value is
This variable specifies a mirror URL which will used by cpanminus to install dependencies. By default the URL is not specified.
Set this to "true" to enable automatic reloading of modified Perl modules.
The StartServers directive sets the number of child server processes created on startup. Default is 8.
Number of simultaneous requests that will be handled by Apache. The default is 256, but it will be automatically lowered if memory is limited.
Override PSGI application detection.
If the PSGI_FILE variable is set to empty value, no PSGI application will be detected and mod_perl not be reconfigured.
If the PSGI_FILE variable is set and non-empty, it will define path to the PSGI application file. No detection will be used.
If the PSGI_FILE variable does not exist, autodetection will be used: If exactly one ./*.psgi file exists, mod_perl will be configured to execute that file.
This variable overrides location URI path that is handled path the PSGI application. Default value is "/".
Dockerfile and other sources are available on https://github.com/sclorg/s2i-perl-container.
In that repository you also can find another versions of Python environment Dockerfiles.
Dockerfile for CentOS is called
Dockerfile, Dockerfile for RHEL7 is called
for RHEL8 it's
Dockerfile.rhel8 and the Fedora Dockerfile is called Dockerfile.fedora.
